"I would just like to say that IQFeed version 4 is running very well and I am very happy with its performance. I would also like to extend a big thanks for the fast and efficient help that I always receive. My questions and concerns are always addressed promptly. Way to go!" - Comment from Josh in CO.
"This beats the pants off CQG, I am definitely switching to the ProphetX 3.0!" - Comment from Stephen
"If you are serious about your trading I would not rely on IB data for serious daytrading. Took me a while to justify the cost of IQ Feed and in the end, it's just a 2 point stop on ES. Better safe than sorry" - Comment from Public Forum
"I ran your IQFeed DDE vs. my broker vs. a level II window for some slow-moving options. I would see the level II quote change, then your feed update instantaneously. My broker's DDE, however, would take as much as 30 seconds to update. I am not chasing milliseconds, but half a minute is unacceptable." - Comment from Rob
"Thanks for the great product and support. During this week of high volume trading, my QuoteTracker + IQ Feed setup never missed a beat. Also, thanks for your swiftness in responding to data issues. I was on ******* for a few years before I made the switch over early this year, and wish I had done it a long time ago." - Comment from Ken
"Everything is working amazing now. I'm already impressed with the true-tick feed of IQFeed and it's ability to support my 480 symbol layout." - Comment from Tyler via Email
"I "bracket trade" all major news releases and I have not found one lag or glitch with DTN.IQ feed. I am very comfortable with their feed under all typical news conditions (Fed releases, employment numbers, etc)." - Comment from Public Forum
"Everything is working great ! Very impressive client. The news refreshes better and is more pertinent than the ******* feed I paid $ 100/month for. I Also like the charts a lot." - Comment from Leon
"Interactive Brokers tick data was inconsistent, so I have switched to using DTN exclusively. It is great to no longer have to worry about my datafeed all day long." - Comment from Philippe
"This is an excellent value, the system is generous (allowing for 500 stocks) and stable (and really is tick-by-tick), and the support is fantastic." - Comment from Shirin via Email

I downloaded minute candles for PFPT for 3/9/2016 , and I see some candles are missing, such as:
13:02
14:23
14:33

Maybe some other minute candles are missing....

Please explain

If the stock didn't trade during those minutes, there won't be a bar.

Is there any possibility to get these 'missing' candles filled (with previous values) directly from the feed?

Or do i have to manipulate the data afterwards in order to have all minute values filled?

Good morning,

You would need to manipulate the data to suit you if you would like to see bars during these lulls in volume.

When retrieving historical data with 'Interval TimeFrame' (1 sec interval), i also get missing values. (Different seconds do not appear on the feed). You said this may be because there were no trades on that certain period, but, with Interval TimeFrame Requets, I am not getting trade values, but close values.

So it is not supposed that it has always to be a Open/High/Low/Close value for every interval requested? If there was not a single trade, this values would just be flat, but it seems that im not able to get a complete feed with second intervals.

Here you can se, that for example, i do not get 10:00:03 or 10:00:04 values for QHO# 'Interval TimeFrame' (1 sec interval) requesting:

[0] Close 1.4571 double
Date {12/07/2016 10:00:01}

[1] Close 1.4571 double
Date {12/07/2016 10:00:02}

[2] Close 1.4568 double
Date {12/07/2016 10:00:05}

Is it possible to do something with that?

Jose

Good evening,

We do not create any data points or bars for times where no data exists. So this would be the expected behavior for us.
